气孔蒸腾中保卫细胞原生质的调控作用

Modulation effect of protoplasm in guard cell on stomatal transpiration

气孔运动的机理一般公认为保卫细胞的渗透调节。作者所在研究小组近几年的工作表明：动物神经递质乙酰胆碱参与气孔运动的调节；植物细胞骨架微管、微丝在气孔运动中起重要作用。因而提出保卫细胞原生质在气孔蒸腾中的作用值得进一步研究。

Stomatal movement is supposed to be mainly controlled by an osmo-reguIatory system.Our recent research results indicate: (a) Acetylcholine, an important neurotransmitter in animals,is involved in regulation of stomatal movement. (b) There are evidences demonstrated that therole of guard cell cytoskeleton in stomatal movement. We suggest that the protoplasm of guardcell involved in stomatal movement.
